The deposit made in BK8 will be credited 100% in special bonus with a requirement of 6x? I understand that a minimum wagering requirement is the deposit +100% and this is x6, isn't it?
That's right the total deposit + bonus that must be stake and 6x roll over is quite low because usually the casino requires higher than that it can be up to 40x, so you have a chance to be able to fullfill the requirement and make withdrawals, but it would be better for you to check correctly what game whose stake will be counted for this bonus.
